In the power system, the wiring accuracy of the protection loop and the metering loop is crucial, which is directly related to the stable operation of the grid and the accuracy of the electricity metering. Due to the increasing complexity of wiring protection devices and high-voltage metering devices in modern power systems, incorrect wiring can not only lead to unstable operation of the system, but also facilitate electricity theft. To this end, the company has specially developed a protection loop vector analyzer to provide an efficient and accurate test tool for power workers.
Key features: Phase meter function: It is used to verify the correctness of the wiring of the main transformer differential protection and bus differential, and ensure that the protection device can operate correctly when a fault occurs.
Electrical parameter tester function: test key parameters in the power system, such as voltage, current, power, etc.
Metering wiring detector function: detect the three-phase three-wire electric energy metering wiring, and effectively prevent the loss of electricity charges caused by wiring errors.
Harmonic content test function: analyze the harmonic content of voltage and current in the field to help users understand the power quality of the system.
Oscilloscope Function: Provides a simple oscilloscope function for observing the waveform of the test signal.
Features: Multi-channel display: 9-channel vector display on the same screen, which can measure 3 voltage and 6 current analog at the same time, which greatly improves the test efficiency.
Safe and convenient: The clamp current transformer is wired, and there is no need to disconnect the current loop, ensuring the safety and convenience of the test process.
Intelligent analysis: It can carry out vector analysis of complex protection devices, automatically judge whether the wiring is correct, and provide the correct wiring diagram for users to compare.
Multi-functional integration: It integrates many functions such as electrical parameter testing, harmonic analysis, oscilloscope, etc., to meet the different testing needs of users.
Humanized design: large screen, high-brightness color LCD display, all-Chinese character graphical menu and operation tips make the test process more intuitive and easy to operate.
Efficient power supply: Powered by large-capacity lithium battery, it can work continuously for up to 6 hours to ensure long-term test work.
Data storage and transmission: It can save more than 2000 sets of test data, and support data upload to the background management computer for comprehensive analysis.
Convenient to carry: small size, light weight, especially suitable for on-site use. At the same time, the reserved USB port allows it to be used as a removable storage device.
The protection loop vector analyzer is an indispensable assistant for power workers, which can not only improve the efficiency of testing, but also ensure the stable operation of the power system and the accuracy of electricity metering.
